Tennis world number 1 naomi osaka signs with nike

I think there may be some incorrect information here!

Naomi Osaka is indeed a world-renowned tennis player and the current world No. 1 in women's singles tennis, but she has not signed with Nike.

Osaka has been sponsored by Adidas since the beginning of her professional career, and she has been one of the brand's most prominent ambassadors. In fact, she has been wearing Adidas apparel and footwear during her matches and has appeared in several Adidas marketing campaigns.

So, to clarify, Naomi Osaka has not signed with Nike, but rather remains a loyal partner with Adidas.
